As known, nitrogen could form 3 bonds based on octet rule, because it has 5 valence electrons. That means it needs 3
<span>The correct answer as to what the Aufbau principle states is B. electrons will be added to an atom starting from the lowest possible level or sublevel. First, these lowest levels have to be fulfilled before going into the higher levels of energy, in order to make the matter balanced and in harmony, until the perfect electron configuration is achieved - the one which is stable. The word Aufbau is a German word that means "building-up."</span>
The ionic compound formed by sodium and sulfur is Na2S, whose name is sodium sulfide.
The chemical formula tells you the ratio between the two elements is 2Na/1S or 1S/2Na
So, if you have 6.4 * 10^22 sodium ions, you will have
6.4 * 10^22 Na * 1S / 2Na = 3.2 * 10^22 S.
Answer: the compound contains 3.2 * 10^22 sulfide ions.
Answer:
Firsthand association assigns energy throughout conduction. Radiation transpires when particles consume energy that progresses as a wave. The heat will run from the h2O to the ice continuously until the ice has absolutely melted so both elements have reached the same temperature.
